The Differential Compound Engine - Part 2: Transient Response of the Differential Compound Engine (DCE) Compared with Conventional Turbocharged Engines 740722
The paper describes experimental and analytical results for transient response of a prototype differential compound engine (DCE). It is shown that the transient response of the DCE is particularly favorable due to two inherent features: the low inertia associated with the fully floating epicyclic gearbox and inherently favorable trapped air fuel ratios.
Comparisons between a hypothetical DCE and a similar turbocharged engine installed in a 24 ton truck bear on the findings on the prototype unit.
